According to the preferred emoodiment of our invention shown on the accompanying drawings, one and the same power-driven cam shaft is employed for operating the several mechanisms which comprise the machine.

Clutch-control and power Connections for @am shaft Referring more especially to Figures 1, 2, 3, and 4, a cone pulley 1 which is driven by an endless belt 2, is journaled freely upon a power' shaft 3 to which is splined a clutch block 4, said power shaft being journaled in axially-spaced bearings 5 and 6 carried by one of the side frames 7 and 8. Slidable within a peripheral groove 9 in the clutch block 4 is a'segmental block 10 which is mounted on a stud 11 carried by a rock-arm 12 which is secured to a rock-shaft 13. Said rock-shaft is oscillatably mounted in a bearing 14 and at its outer end movably supports a crank arm 15 provided with a handle 16. A laterallyprojecting pin 16 on the main frame of the machine serves to limit the displacement of crank arm 15in` one direction under the ten*r sion of a spring 17 said spring 17 being ccnnected at one end to a pin 18 which jrojects outwardly from the side frame and at its other end to a pin 19 which is presented downwardly from the hub portion of the crankarm 15. Said spring 17 tends to hold the crank-.arm 15 against the pin 16. i tension spring 2O shown in Figures 2 and 3 is connected at one end to a pin 21 presented inwardly from side frame 7 and at its other eid to the hub portion ofthe rock-arm 12.y Tin spring 2O tends to hold. the .clutch block 4 in clutching engagement with a fixed braking element 22 rigid with the' bearing Projecting inwardly'from the crank arm is a pin 23 adapted to vengage one arm a bent lever which is keyed to rock-shaft 13. the other arm 25 of said bent. lever being adapted to be engaged and supported rby a lug which as shown in Figure 3 projects from thelower end of a latch-arm 27 which is pivotally suspended from a fixed pin. 28 and provided with a rounded l-:nob 29. It will be understood from thisdescription that whenever the crank-arm 15 is moved into engagei'nent with the arm 24 oli' the bent lever, block 4 will be moved ont ci e with the braking element` f ingl engagement with the con sets theinachine in motion. it eine time the arm 25 is liftedebove the lug of latch-erm 27 which meint *l e latch-arml27 is moved to release positif" Silbfeealz'ng mechanism Referring more especially to Figi d 4., a, Spiral gear which iskeyed to the cam shaft 32, meshes with. e` spiral n in ""fl which is keyed to the lower enl or on inclined shaft 34.

Pivotally mounted on spin 58in the erm 57 is n dog or brekeilwhichis provided with a spring` 6() which edsptsit to grip the silk or cord on its downward movement but permits the silk or cord to slip through the tubular .guide during the upward movements of the latter. As indicated in Figure 2, the bosses or sockets 56eme carried by oppositely-presented arms 6l and 62 mounted on e poi-1t or carrier 63 which es shown best in Figure 4 is mounted on a. verticallymeciprocztble plunger G4. Said plnngerf64 slides in a boxdike guide 65 and at its lower end carries a bracket arm @5a-with a depending lng 65h. To e pin 65C carried by the dependingl lug 651? is pivotztlly` connected the outer end oi' ai cam-erm 65d which is oscilletedon a lined pin 65@ by meansot a cem-roller Gf operating' in s com groove 65gof a, cem 65h which is keyed to coin-shaft 32.

lllechansmrfm looping the sil/c As shown in Figure 7, the silk strand as Vit depends from 'the Asilkguide or needle hangs in the gripping plane of the silk grippers 81 and 86. Reciprocable in this plane is aplunger which is slidably mounted in a guide bracket 96`mounted on the top V Y plate or` table 41.A Articulately connected to the rear end of the plunger 95 is one arm 97 of a cam lever which is pivotedat 98 in abracket 99. p The cam arm-100 of said cam lever is provided with a roller 102 which operates in a cam slot 103 inthe peripheral face 'of a cam 104 which is keyed to the cam shaft 32. The construction and arrangement of saidlcam is such that the silk-looping plunger is reciprocated once between the time that the silk guide reaches its upper extremity of movementv andbegins its downward movement therefrom. As shown best in Figure 7, the silk guide in its upper position is arranged immediately above the silk-looping plunger 95, said plunger being provided with a longitudinal groove 105 Vfor guiding the silk during theV movement' of said plunger while drawing the silk into anopen loop. At its forward end, said looping plunger is `provided with a lip or finger 106 which overhangs a spring finger 107 which is provided at its outer end with a V-shaped hook or linger 108 which by means of a leaf-spring 110 is yieldably retained in its normal position as shown best in YFigures 30 and 31. As shown in Figure 7, .after the guidev or needle 49vhas descended to present the end of the silk to the silk grippers and again moved upwardly to make way for the looping plunger 95, said looping plunger as it moves forwardly draws the strand of silk tight over a part-circular guide or recess 109 while drawing the silk through the guide or needle into an open end loop.

During the forward movement of the silklooping plunger 95, the lower end of the n'l of silk anchored between the silk- A, piping slide 81 and block 86 whileat the saine time, aY supply of silk is being drawn under the spring-pressed dog or brake 59. Asthe inclined outer edges of the V-'shaped hook or guide 108 strikes Vthe tautly-drawn silk, it is displacedlaterally until the silkl slides into the angular notch within the hook or finger 108 so that upon the return move- Y ment of the plunger 95, said linger will act as a drag on the strand of silk.

cording to Figures 1 and 3 of the drawings,

is a box-like housing 111 within which is reciprocably 'mounted a rack or ram 112. A Vflat bar 112 which is presented endwise from the ram 112 is provided at its outer end with a hook or gripper113. Meshing with the rack bar 112 is a spur gear 114 which as shown best in Figure 19 is keyed to a rotary shaft 115, said shaft beingv journaled in the top `plate or table 41 and abearing block 116 carried thereby. Also keyed to the shaft 115 is a smaller spur gear 117 which meshes with a segmental rack 118 carried by a radial arm119 keyed to a rotary shaft 120. `This rotary shaft is also journaled in the top plate or table. Keyed to the lower end of rotary shaft 120 is a cam arm 121 which as shown in Figure 19 carries a cam roller'122 operating in a cam lslot 123 in the peripheral face of a cam 124 which is keyed to the .cam shaft 32. It will be understood from this description that as the cam rotates, the cordlooping ram will be reciprocated periodically in such a way as to present the hook or gripper 113 through the looped silk and open recess in the forward end of the silk-looping plunger 95.

gripper and mechanism for oopeclkv silla opemzng same spur gear 132 on the lower end of the hol-` low spindle 93 which is oscillatably mounted in the bearing boss 94 in the top plate or table 41 as described above. Secured to the upper end ofthe hollow spindle 93 by means of aset screw 133, is the hub portion 134 of a radial arm which comprises an under plate 135 and an upper plate 13G. Arranged between said plates as shown best in Figure 11, is a sector-like plate 137 which is pivotally mounted upon a pin 138 extending between said axially-spaced plates. A leaf spring 139 which is secured at one end by a screw 140 to the hub portion 134 of said radiale-rm, presses at its outer end'against a flat surface 141 on the sector-like plate 137 and thus tends to maintain saidplate in the position shown in Figure `11. Secured to the outer edge of the sector-like plate 137, as shown in Figure 21, is gripper block 142 which is adapted by a pivotal movement of plate 137 to abut under and upper plates 135 and 136 of the radial arm (see broken line in Figure 11).

The lower gripper block '142 is provided with a rectangular recess or slot 144 in its upper rear corner to accomodate a depending lug 145 on an upper gripper block 146, a transverse pin or pivot 147 forming an articulated connection between said gripper blocks. An upwardlypresented linger grip 146 constitutes a slidable abutment for the upper end ot a leaf spring 147 whichV is secured at its lower end by a screw 148 to the lower gripper block 142. The upper gripper block is provided with a central opening 149 across which extendsa pin 150, said pin being movable within a slot 151 in the upper end of a latch dog` 152 which is reciprocably mounted in a vertical hole in the'lower gripper block 142. At its lower end said latch dog is provided with an angular tooth 152a whereby it is adapted j to interengage with an angular shoulder 153EL on the outer end of an upwardly inclined latch-bolt 153, said latch-bolt being reciprocably mounted in a tubular socket 154 extending through the top plate or table. The outward displacement ol said latch-bolt by a compression spring 155, is restricted by j a set screw 156, the inner end of said set screw being presented within a longitudinal groove 157 in the under side of said latchbolt. The compression spring155 is mounted on a reduced portion of the latch-bo-lt which slides in a bushing 158. A collar 159 limits the outward throw of the latch-bolt un1 der the pressure of compression spring 155. The upper and lower gripper blocks 1,46 and 142 are provided with gripper jaws 16() and 161 which are suitablyformed to admit and close upon the double strand or" silk presented thereto.

.Rotary /mot-tg/ng chuck ma? opera/ting connections therefor As shown inV Figure 7, two axially spaced bearings 162 and 163are `secured to the top plate ortable and as shown in `Figure 1, said bearings are arrangedslightlyout ot l alignment with* the axis of the silk-looping plunger. Journaled in one oi these bearings is theelongated shank 164 oi animproved knot-tying chuckwhich is provided withfa laterally-presented cord-grippingV jaw 165. The shank 164 is provided with a longitudinal slot or recess 166 within which lits the complementary shank-portion 167 oi a secondcord-gripping jaw 168.` The shank-portion 167 is shorter than theV slot or recess in tbeshank 164 so as to permit the opening and closing of 'the jaws 165 and 168 by an endwise movement of the shank portion 167.

mally closed, form a tapered horn about which the strands are temporarily coiled one after the other during` the knot-tying oper ation. i f Y As shown in Figure 22, the complementary shank portions of the relatively mov able cord-gripper jaws togetheriorm a round body rotatable in the other one of the bearings. The reciprocatory shank 167 carries at one end a cylindrical collaror flange 169.

Saidcollar or flange is provided with aA slot 170 by means of Vwhich it is non-rotatably but slidably mountedon the shank 164.` Said collar or flange isrotatable withina hollow bearing block 171 providedwith oppositely presented pins 172 which as shown in Figures 2 and 8 rest within the slotted upper ends of a bifurcated lever arm 173 of a cam lever whichis oscillatory mounted on a stud 174.` .The other arm 175 of said cam lever is provided'with a cam roller operating on a cam 176 which is keyed to the cam shaft. It will be understood that a rotation of said cam will impartsuccessive. relative axial movements to the movable gripper jaw and thusproduce periodic cord-gripping operations 'duringthe continued operation ofthe machine. Suitable means forlresisting the opening movements of the gripper may be .provided as follows. 164-is held against axial displacement by means of fixed collars 177 and 178 on opposite sides ofthe bearing 163. Interposed between the collarl-177 and the hollow bearing block 171 is a compression spring 179 which is com` pressed by the cam for opening the gripper jaws and permitted to expand for closing said gripper jaws. Keyed tothe elongated gripper shank 164 is a spur gear 180 which meshes with a segmental rack 181. As shown bestin Figure 9, said segmental rack is carried by one arm'182 of a Vcam-lever which is `pivotally mounted upon a studV 183, the other arm 184 of said cam-lever being provided with a cam roller 185 which moves in a cam-groove 186 in the lateral taceof a cam 187fsaid cam being keyed to the cam shaft.

silk. During this return movement of the ram 112, the doubled cord is disposed above the closed gripper jaws oi' the knot-tying chuck while `the return movementof the silklooping plunger has left the loop end of the silk anchored upon the doubled cord as indicated in Figure 28. `Suitablemeans for prea i d venting lateral displacement of the silk dur- The gripper jaws 165 and 168, which are nor j ing these movements, may be provided as follows. Reciprocably mounted in a housing 188 (see Figure 1) 1s a rod 189 which carries The elongated shank isc an arm 190 provided' at its outer end with a deflected finger or guard 191 which moves approximately inline with or a little to one side of the axis of reciprocation of the silklooping plunger. As shown in Figure 1.the rod. 189carries a laterally-presented pin 192 which oscillates in the bifurcated upper endA of one arm 193 of a cam-,lever whichismounted on a stud 194. The other arm 195'of said cam-lever is actuated' by a cam 196. which is suitably formed to impart .the movements indicated by the positions'of said guard finger shown in Figures 27 t-o 32. inclusive. of the drawings. l

Y As shown. in Figure 30, the guard finger 19.1 is withdrawn from its.operativejposition as the closed jaws of the knotftying chuck begin to revolve in the direction indicated by thel arrow. In the meantime, the oscillatably mounted silk-gripper'has beenmoved by its Cain-operated connections into the position shown'in Figure 3.0.. As shownin Figure 21, the: jaws of the silk-gripper are opened as theyY approach the doubled strandof silk by reason ofthe 'latch-dog. 152 riding over the raised end of latch-bolt 15.3. Asv the. latchdogv 1'52 leaves said latcli-dol );,the gripper jaws close upon thesilk. At about this time, as indicated in Figure 12, a forwardlypresentedpin 197 on the lower gripper-block, comes into engagement. with the protruding end of a rack bar 19`8which is normally retained in the position shown in Figure '12', by a compression spring 199 which is'interposed between said rack-bar; and a screw plug 200. As the rack-bar moves. inwardly, aasmall spur gear 201 which meshes therewith isrotated. in a clockwise. direction on' its pintle 202. Secured to thev lateral face' ofspurjgea-r 201 is a curved arm 203-provided1initsouter end with a slot 204 withinwhich a'stud 205 is adjustably mounted, sa-id stud being threaded into a cutter blade 206.r Secured tothe lateral face of the lower gripper block by means:V of a screw 207 is an arm 208 provided with an angular notch 209 in its outer end. Said notch 209 adapts the arm 208 to serve as a combinedy guide and support for the double strand of silk and as shownin Figure 30l the outer end of arm 208 is offset to permit the cutter blade 206 to descend between it and the gripper. After the silk has beensevered in this manner the continued rotary movement of the knot-tying chuck operates to wind the doubled silk around the neck of said chuck adjacent to the laterallypresented jaws and as said jaws approach their position shown in Figure 31, the movablejaw opens and permits the doubled cord to fall between the open jaws of the chuck. As the lchuck jaws. close upon the Vdoubled Cord, the` direction of movement of said chuck isreversed as indicatedy in. Figure 32 and at the same time the doubled cord is severed. For this purpose, the following device may be employed.

' Oord-severing mechanism Referring more especially to Figures 2, 7, 30, and 32, a cutter blade 210 which is provided with an inclined vcutting edge 210a as shown best in Figure 7, is secured by a screw 211 to a pad or block 212 at the upper endof a curved arm 213 of a cam-lever which is pivoted upon a stud 214. The other arm 215 of said cam-lever is provided with a carnroller 215L which operates over the face of a cam 216 which is keyed to the cam shaft.

As. the knot-tying chuck rotates from its position `shown in Figure 32 inthe direction indicated by the arrows to its position indicated in Figure 3.3, the pointed shapev of the cord-gripping jaws permit the doubled silk to slip oil' of said aws while the Vsevered double end of cord is formed into a loop as shown in Figure 3 3. Asthe closed jaws. continue their upward movement from the position shown in Figure 3.3, the looped double cord slips from the pointed gripper, jaws as the ends of said cord is drawn therethrough about the doubled strand of silk. This stage of the operation is shown inFigure. 34. lm-

mediately thereafter the gripper jaws open as shown in Figure35 after which the. return swing of the silk-gripper draws the knot tight as shown in Figure 36. By referring again to Figure 21, it will Vbe understood that if, for any reason, the silk-gripper is released before the return swing of its supporting arm, the latch-bolt would yield sufliciently to permit the passage of the latch-pin carried by the gripper.

Keyed to the `outer end of the rotary shaitt 219 (see Figure 17), is a lever arln 238 whichis provided on its outer end with a claw or hook 239 for engaging the looped cord of `a iinished` tassel.V

During the forward movement oi rack 228, the spur 238 has swung through an angle oi approximately 130 degrees when its angular ,inoveJ nient is interrupted by a yleldaloly lnountedA stop 240 supported by a compression spring 241 as shown best in iligure 26. A pedestal 2112 houses the` yieldably inounted'stop 2l() and is provided with laterally-spact-zd guides between which the claw arin 238 is adapted 'to slide under the continued forward movement This, sliding movement causes` the ,claw 239 to pass between the strands of the looped cordso that upon the EN return movement of said lever the claw 239 detachee the finished tassel troni the. silk` gripper andcord-looping hook and delivers it to-one ot' a plurality of radial arms of a counting head 2&4 (see Figure 1). From an inspection of Figure 1,: it will be noted thateach of the radial arnis 243 is provided on its outer end with a slotted post 2li-the slot in said post heing adapted to receive the edge of the claw-lever which strikes such post in such a way that the tassel loop is thrown over and hangs upon said post. rlhe construction and operation of the counting mechanism is such that after apredeterinined nuinber of the tassels have been lodged upon one of theradial arins 243, said arin is automatically advanced and another moved into charging position.

v`Suitable means for coordinating the operations ot the counting mechanism with the remainder oi the machine may be provided as follows. A depending bracket or support2l6 may be provided with a loopend 2li? within which a bolt 24l3niay be adjusted, said bolt being secured to the reciprocatory rod which Pivotally mounted at 249 on the outer end of said bracket or support is a pawl 250 which at each operation oi' said reciprocatory rod iman angular movement to a ratchet 251. l dog 252 which is pivoted at 253, prev-ents a retrograde movement oit the ratchet. After' a predetermined nuniber of tasselshave been delivered to one of. the radial arnis, a stop is automatically retracted ifroin the circular path of a top plate 255 on the rotary head 244, thus permitting a restarting of the pers, the silk-looping gear 227 rotates until the claw arin countingmechanism for the next Vgroup of tassels. j j
